(lontinuation of application Serial No. 848,999, filed Dec Serial No.

Be it known that I, FRED Ci'HORAK, a citi have invented a new and usefulMower, of which the following is a specification. I

The invention relates to improvements in mowers, and the presentapplication is filed place of a former application, SG-f rial No.348,999, filed by me on orabout Dec. 21 1966, for a similar device. 1

he object of the present invention is to the mower frame, independentlyof the tongue, to a point close-to the round; so as itman not onl in inewith but y the same p ane as the cutter barto do away withthe downwardthrust or pressure and the consequent friction incident clination,whereby the mower is operated ditu're of less power, whileits durabilityis increased and the noise lessened.

With these and-other objects in view, the invention 'consists'in' theconstruction, and novel combination'of parts hereinafter fullydescribed, illustrated in the accompanying claims hereto ap endcdyitbeing understoodthat varione o .anges in the form, proportiomsize andminor details of construction, within the scope of the claims, may beresorted to witl1- out departing from the s irit or sacrificing an ofthe advantages of tlib invention.

11 the drawings :-Figure 1 is a perspecance with this invention, thefront end of the mower frame being at the limit of its downwardmovement. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 isa simi- Like numerals of reference designate corresponding parts'in allthe figures of the drawlngs.

In the accompanying illustration, the iningtype, but the improvementsare equally other forms of machines, such as .the McCormick mower. Themain frame 1 of the machine is constructed in substantiallythe samemanner as the main frame 7 or a Deering' or McCormick mower with theSpecification of Letters Patent.

ember 21, 1906. This exception that it is provided at the right handside with an extension 2, formed by elongating the usual channeledtonguere- 'ceiving seat, and provided at the front with an upwardlyextending oblong yoke '3, composedof parallel sides and connecting topand bottom. portions and having its lower portion formed by the sidesand bottom of 'the extension 2 and receiving the tongue 4. The tongue'4is secured at itfhrear end to the lugs or ears 2" of the extension 2 atthe rear end thereof by a transverse ivot 5, which permits the frontportion of tie main frame to be raised and lowered independently of thetongue.

In practice, the front end of the main frameof a McCormick or Deeringmower 'is about eight inches above the ground, andthe. left hand ordrivin end of the pitman 6 ,is considerably. hig erthan the sickle orcutter bar 7. This results in a downward thrust, which roducesconsiderable friction and increases the power necessary to operatethecuttinga paratus. The yoke enables thefront end frame, which carries thecrank wheel 8, to be dropped close to the ground so that the pitman islowered from an inclined position to substantially a horizontalposition. By bringing the itman not only in line with but in substantiaof the mainor cutter bar, the friction 1s greatly reduced,

the cutting a paratus is rendered more effective, and t e durability ofthe mower is increased. Also this change in the arrangement of thepitmancauses the mower to operate with less noise than heretofore.

The main frame is raised means of an o' crating lever 9, provided at itslower end wit a short forwardl extending arm 10, arran ed at substantialy right angles to the b0 cured by a pivot 11 to the side of the tongue'at a point in rear of the yoke.

connected with the inner sideof the yo e at a point near the centerthereof by means of the piic lot 1'1, piercing the outer end of the arm10 an ver 9 is ada ted to be oscillated backwardly and forwan ly toraise and lower the'yoke and the main frame of the mower, and it islocked in its adjustment by means of a dog .or detent 12, connected witha latch lever 1.3 and arranged to engage. a toothed segment 14,

and lowered by y portion of the lever and se The lever 9, which extendsupward from the ton ue, is'

the adjacent side of the yoke. The lemounted on the tongue adjacent tothe lever. The latch lever 13 is mounted. on the operating lever 9contiguous to the hand e or grip portion thereof, and is adapted to begrasped simultaneously with the same in the usual manner. By adjustingthe operating lever ti, the front end of the mower frame may he arrangedclose to the round, and when. the character of the surface of the groundrenders it necessary, it may he raised to a greater or less degree toenable it to clear rough surfaces and other obstructions.

The main frame is mounted on the axle in the usual manner, and gearingoi the ordinary construction is employed for operating the cuttingapparatus, which. is connected with the main frame by the usual forkedcoupling 15.

In practice the mower will be equipped with the usual operating leverfor adjusting the cutting meol'ianism, and as these various parts of'the mower are well known in the art and do not constitute a portion ofthe present invention, detail description-and illustration thereof aredeemed unnecessary.

Having thus fully (.lescrihed my invention, What I claim as new anddesire to secure by Letters Patent, i; 1

1. in a mower, the combination with an iL'XiG, of a'main frame mountedon the axle and provided at the right hand sideuith. a yoke, cuttingmechanism, gearing for operating the cutting mechanism including a crankwheel mounted on the front of the main frame at the left hand sidethereof, and a pitman extending from the crank wheel to the cutter herof the cutting apparatus, a tongue pivotally connected with the mainframe and passing through the said yoke, and means for adjustahiyconnecting the main frame and the tongue, whereby the front end of themain frame is lowered to arrange the pitman in the same horizontalplaueas the cutting apparatus and is raised to clear obstructions.

2. in a mower, the comhinatioi': with an axle, of a main frame mountedon the axle and provided at the right hand side with a yoke, cuttingmechanism, gearing for operating the cutting mechanism including a crankwheel mounted on the front of the main frame at the lefthand sidetherwf, and a pitman extending from the crank wheel to the cutter hiirof the cutting apparatus, a tongue pivotally connected with the mainframe and passing through the said yoke, adjusting-means connected withthe tongue and with the yoke and including an operating lever, a toothedsegment, and a dog or detent carried by the lever for engaging thetoothed segment.

3. In a mower, the eomhination with an axle, of a mainframe mounted onthe a de and provided at the right hand side with a yoke, cuttingn'ieclianisuu gearing for operating the cutting mechanism including acrank wheel mountedon the front of the main frame at the left hand sidethereof, and a pitman extending from the crank wheel to the cutter herof the cutting apparatus, a tongue pivotally connected with the mainframe. and passing through the said yoke, 2m adjusting lever fulcrumedon the tongue and having a short arm connected to the yoke, and meansfor locking the lever in its adjustment.

In testimony, that I. claim the foregoing as in F own, I. have heretoaflixed my signature in the presence of two witnesses.
